SNOW- PLOW ATTACHMENT TO LOCOMOTIVES.

' SPECIFICATION forming part of Letters Patent No. 294,383, dated March4, 1884.

' Application filed March 12, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK HAINS- WORTH, a citizen of the UnitedStates, residing at the city of Chicago, in the State of Illinois, haveinvented certain new and useful Improvements in Snow-Plow Attachments toLocomotives,of which the following is. a specification.

The nature and object of this invention are to provide an attachment tolocomotives, Worked by a rotary engine-independent of the speed of thelocomotive, to clear the track from snow.

Figure l is a longitudinal view of a locomotive, showing my snow-plowattachment. Fig. 2 is a front end view, with portions of cowcatcher cutaway to clearly show the front twistedshaped fan-wheels and knives.

This device can be attached to any locomotive. V

A is a rotary engine attached to the boiler and to the frame of thelocomotive by suitable means and stays, as at h, and located at the sideofthe locomotive, in advance of the drive-wheels, and fed by steam fromthe boiler through the pipe a.

D D'is a shaft passing through the rotary engine A, and serving as itsaxis, placed alongside of boiler, and working in suitable bearingsattached to the frame and boiler.

At the front and rear ends of the shaft D D are placed twisted orscrew-bladed fan-wheels B B, and a little in advance of the frontfanwheels are attached the revolving knives C C. These twisted orscrew-bladed fan-wheels work sufficiently close to the rails so that inrevolving they clear the snow from the tracks. (See Fig. 2.)

e e is the valve-rod working the valve 1; in

steam-pipe a, and extending to the cab at f, Where it is worked byengineer.

1' is the discharge-cock in the rotary engine, for the discharge ofwater from the cylinder.

01 is the exhaust-pipe leading from the ro-' tary engine to thesmoke-stack.

g is a bracket attached to the boiler, and holds the rear end of theshaft D. It'will be observed that there are two of these shafts locatedat each side of the locomotive and each 5o propelled by a rotary engine,and also each has twisted or screw shaped fan-wheels revolving knives.

The knives O G serve the purpose of chopand ping or cutting the snowwhen baked or packed, which enables the revolving wheels to readilyremove it. The edges of the wings or fans or blades of the screw-bladedwheels are made sharp, so as to cut or loosen the snow. They are turnedor twisted, so as to be parallel in their face to the rail, so that inrevolving they will throw the snow to each side of the track.

It will be observed that the shaft D D is fan-wheels will enable them toremove all the snow on'the track, and thus the danger of disabling thelocomotive and injuring the train entirely disappears.

I am aware that screw-bladed wheels have been shown in conjunction withsnow-plows; but the arrangement and combination with a locomotive, asherein shown, is believed to be new.

I claim 1. The rotary engine A and revolving shafts D D, arrangedalongside of boiler, provided with twisted-shaped fan-wheels B B, incombination with a locomotive, as and for the purpose shown.

2. The rotary engine A, revolving shafts D D, arranged alongside oflocomotive-boiler,

vthetwisted-shaped fan-wheels B B, and knives O O, in combination with alocomotive, as and for the purpose shown.
